Sexual Agreements Among Young Sexual and Gender Minorities Assigned Male at Birth: Associations with Relationship Quality and Break-Up.

Previous studies have shown that sexual non-monogamy is not associated with lower relationship satisfaction among adult male same-sex couples and may therefore be a viable alternative to monogamy. However, sexual minority men with non-monogamous agreements have reported lower commitment and trust in their relationships than those with monogamous agreements-potentially raising their risk of break-up. In this study, we investigated whether sexual agreements (monogamous, non-monogamous, or no sexual agreement) were associated with relationship quality and rates of break-up over 1 year in a sample of 338 young sexual and gender minorities assigned male at birth (SGM-AMAB). Participants reported their sexual agreement and indices of relationship quality (satisfaction, trust, and commitment) at baseline, as well as their relationship status (intact or broken up) at 6- and 12-month follow-up. Results showed no significant differences by sexual agreement in concurrent trust, but participants with monogamous agreements reported higher satisfaction and commitment than those with non-monogamous agreements or no sexual agreement. Despite these significant differences in relationship quality, there were no significant differences in rates of break-up at 6- or 12-month follow-up across the sexual agreement types. However, having a monogamous agreement was indirectly associated with lower rates of break-up through relationship commitment. Although results were mixed, findings provide some preliminary support that young SGM-AMAB in relationships with monogamous agreements may have higher satisfaction and commitment at early relationship stages, and that monogamous agreements may be a protective factor against break-up over 1 year through the mechanism of relationship commitment.
